I don’t think it cares what button I push, but when I select a playlist in the Rockbox firmware it asks me if I want to delete the dynamic playlist rather than playing it (like it used to). I’m afraid if I accept it’s going to erase the playlist. (I used to be able to push right button/fast foward on a playlist in the files list to play a playlist)
EDIT: I either figured it out or remembered how to play a playlist in Rockbox’s files menu. (press center button…now that I think of it…I believe its mostly forgotten more than figuring it out. I’m so used to starting playback of everything with the right button in the OF’s listings)
Until I figure out what is going on I’m going to switch back to Orignal Sansa Firmware…which works.

Rockbox is referring to the “playlist” it is currently playing. It considers everything you play as a “playlist”, so if you want to change to a different Artist or folder containing different songs, you will get this warning msg. (which btw I believe you can turn off in the settings if you want to). 
Oddly the issue resolved itself and I can press the right/fast foward button to play my playlists again…that was wierd.
